Apple has also upped the number of cameras that can be used with HomeKit secure video at each of the different tiers, and users on the lowest $0.99/month plan can now get started with a single camera. Now, users who are paying for any iCloud storage at all - even the $0.99/month 50GB plan - will be able to take advantage of new features such as Hide My Email, iCloud Private Relay, and even use their own custom domain with iCloud Mail.
Apple hasn’t changed the pricing of its paid iCloud plans, so the plus designation is largely just a name change to reflect the new bonus features.
